Sauvignon Blanc nearing dryness?

The Sauvignon Blanc is puffing away. Some are probably pretty close to the finish. I haven't looked or opened the chamber in a couple of days, and the AC is still keeping it cool. I'll remove the AC tomorrow afternoon, so the juice can finish and hopefully without problems. With the higher temperatures in the fermentation chamber (around 56-57 average), and the issue a few days ago when the AC didn't kick in, the fermentation has been going faster, and I have been smelling the familiar yeast smell in the garage.
